Abstract

A parking locking system for an articulated or swing-type tricycle. A parking lever mounted to the handlebars of the steerable wheel actuates a cable and a rod. The rod engages a spring loaded slideable pin member into a hole in a plate fixed to the front frame of the steerable wheel. If the pin is not aligned with one of the holes in the plate, the spring will deform and the pin will slide relative to the rod. Upon further rotation of the front handlebars to a position where the pin member is aligned with a hole, the compression in the spring will cause the pin to interengage with the fixed plate thus locking the front steering wheel. The actuation of the cable interengages locking arms with a plate attached to the front of the swing shaft and with a parking gear in the drive train, respectively. A spring-loaded lever resisting interengagement of the locking arms is used to create tension in the cable and retract the locking arms when the parking lever is deactivated.
